基于ZigBee和GPRS智能监测的节水灌溉装置设计

摘要

为了提高农业用水的利用率，解决农业用水紧张问题，提出了一种基于分布式ZigBee 和GPRS无线通信技术的大范围远程控制节水灌溉系统，实现了节水灌溉装置的远程监控和自动化调节。该系统以单片机作为控制器，将土壤湿度测试数据进行传输和保存，通过设定阈值来控制零压启动电磁阀实施灌溉操作，并采用无线传感网络和GPRS 将采集的数据进行远程传输，实现了定时定量和精确化灌溉。对精细化滴灌系统的过滤器和湿度测试装置的智能监测性能进行了测试，结果表明：该系统可以有效地将过滤器压力和湿度随时间变化曲线传送到远程监控端，且实现了自动化过滤装置的反冲洗功能、滴灌喷头的自动化调节及滴灌的精细化作业。%In order to improve the utilization rate of agricultural water , solve agricultural problems of water shortage , it put forward a distributed ZigBee and GPRS wireless communication technology based on the large range remote control water saving irrigation system .It can realize theremote monitoring and automatic regulation of the water-saving irrigation device .The system took MCU as controller to realize the transmission and preservation of soil moisture testing data , con-trol the zero voltage starting electromagnetic valve implementation of irrigation operation by setting a threshold .It will be collected by wireless sensor networks and GPRS data remote transmission , realize the timing quantitative and precise irri-gation .It tested the last major intelligent monitoring performance of drip irrigation system for fine filter and humidity tes-ting device .According to the test result , the system can effectively filter pressure and humidity along with the time change curve of transmission to the remote monitoring terminal .And it realized the automatic filter backwash functions and the automatic regulation of the drip nozzle , the drip irrigation of the fine operation .
